The paper investigates natural transverse vibrations in a thin rectilinear rod portion of uniform length moving along the neutral line of the undeformed state. The movement occurs between two rigidly fixed coaxial guides (clamps), with the distance between them being equal to the length of the vibrating rod portion. The longitudinal force is assumed to constantly act along the neutral line. It has been found that as the velocity parameter increases, natural frequencies of flexural vibrations in the rod tend to decrease. It has been also shown that as the force parameter increases, natural frequencies of flexural vibrations in the rod show an increase. Using two frequencies of flexural vibrations, we can determine the velocity and force parameters of the moving rod. The results of the work can find technological applications in the dynamics and reliability problems of equipment, machines and mechanisms in the textile industry, thread and cable manufacturing, metallurgy (especially for rolled metal bars and strips), wire drawing, plastic products and paper rolls manufacturing and can be used to determine the velocity and force parameters of a moving rod, metal and paper strip, wire and thread, using two frequencies of flexural vibrations.Downloads
